not spread over the upper or lower surfaces of the .10 sole at the margins thereof.

Further objects reside in the Various adjustments and other novel appended claims. In said drawing,

Fig. 1 is a plan view of the improved blacking machine with a shoe sole mounted in operative position;

Fig. 2 is a side elevation thereof;

Fig. 3 is an end view of the machine looking to the right of Fig. 1, with the shoe sole omitted; and

Fig. 4 is a fragmentary section taken on line 44 of Fig. 1.

I 6 having a pulley disc or collar shaft and 2| of the journal members I4 and I5, respectively, substantially parallel to the shaft IS, the

shaft I9 having a gear 22 meshing with a gear 23 on shaft I6, and having a ring or collar 24 indicated at 59, to serve as a splash guard when the machine The driven shaft [6 is stationary in its modate the thickness of the sole. The sole guide 25 is mounted behind said drivslot 43.

The blacking or inking roller 21 is also adjustably mounted to the arm 26 by the bracket 28 which is pivotally attached at 56 to a connecting of the guiding elbow 25. Hence, ing or feeding members are rotated spective shafts tomove a vertical direction, the edge of the sole is forced against the guide 25 and the periphery of the roll 21, and the sole is thus caused to rotate or turn, in a vertical plane, in such a manner that a single revolution will bring its peripheral edge into when said drivon their reuniform contact with the wet surface of the ing from the spirit of thisinvention as blacking roll 21, which is rotated on its axis by the motion of the sole against said surface. Said roll is preferably made of rubberor other suitable material having a relatively hard andfiat periphery to present an edge to edge contact with the periphery of the sole, so that the blacking or other liquid coating material is thoroughly applied to the sole edge but will not wipe or spread over the edge onto the flat surfaces of the sole. It will be understood that the drive shafts and the feeding mechanism may be operated by any suitable source of power applied to the pulley i1, and it will be appreciated that the sole is rotated and blackened or coated on its edge with extreme rapidity, thereby effecting a very substantial saving in the time and labor required in performing this operation by hand, as well as ensuring a neater and more uniform result.

It will also be understood that the rough or flesh side of the leather sole is presented to the knurled disc or feed roll i8, when the sole is placed in the feeding, mechanism, and that the smooth surface of the complemental feed roll 24 engages the grain side of the sole so that the appearance of the latter will not be marred; and that any other suitable feedrolls may be used in place of the specific types illustrated and described herein. Other changes or modifications in the structural details of the machine herein disclosed maybe utilized without departdefined in the following claims.

I claim: n I

l. Edge-coating apparatus of the character described, comprising opposed feed rolls for gripping the margin of a sole and moving said margin lengthwise, guides bearing against the edge of the sole at opposite sides of the point of contact of the feed rolls, to cause the sole to turn peripherally under action of the feed rolls, one of said guides being a roller for coating the sole edge, and a reservoir for coating liquid located to receive said roller.

2. Edge-coating apparatus of the character described, comprising a pair of feed rolls arranged to grip the margin of a leather sole and hold the sole in a substantially vertical plane, a guiding abutment located to engage the edge of the sole gripped by said rolls, an edge-coating andguiding roller mounted to engage the periphery of the sole, a reservoir for thercoating liquid disposed in operative relation to'said roller, and means for driving'the feed rolls to move the sole downwardly, the said abutment and the engaged edge of said roller being disposed on opposite sides of a vertical plane passing through the feed rolls so that the sole is forced into constant engagement with said guiding elements and is turned by the feed rolls until its entire edge is coated by said roller.

3. Edge coating apparatus of the character described, comprising a pair of opposed feed rolls arranged to grip the margin of a leather sole and hold the sole in a substantially vertical plane, a guiding abutment located above the point of contact between the feed rolls and the sole to engage the edge of the sole gripped by said rolls,- an edge-coating and guiding roller mounted below said point of contact to engage the periphery of the sole, a reservoir for the coating liquid disposed in operative relation to said roller, and means for driving the feed rolls to move the sole downwardly, so that the sole is forced into constant engagement with said guiding elements and is turned by the feed-rolls until its entire edge is coated by said roller, one of said feed rollers being movable away from the other, and spring means yieldingly resisting said movement, so that soles of varying thickness may be gripped be,- tween said rolls. 7

4. Edge-blacking apparatus of the character described, comprising a pair of opposed feeding members resiliently mounted with respect to, each other for movement into gripping relation with the marginal edge of a shoe sole, said members being rotatable onhorizontal axes to feed the sole downwardly, a pair of guiding abutments positioned to contact the edge of the'sole on opposite sides with respect to the downward force applied to the sole, one of said guiding abutments comprising a coating roller turned by contact with the sole, and means to said roller.

5.'Apparatus for blacking the edges of shoe soles, comprising a pair of horizontal shafts, one shaft being pivoted for angular movement with respect to the other, resilient means tending to resist relative movement and to urge the shafts toward each other, opposed feed rolls carried by shafts and adapted to grip the margin of' the sole therebetween, means for romove the sole mara substantially. vertical direcbear against gin lengthwise in tion, a pair of guides adapted to the edge of the moving sole on opposite sides of the unrestrained path of movement of its gripped margin, to cause the sole to revolve with its edge in constant engagement with said guides, one of said guides comprising a roller which is turned by contact with thesoleedge, and means forapplying blacking to said roller to black said edge.

6. Apparatus for blacking the edges of shoe soles, comprising a pair of horizontal shafts, one

shaft being pivoted for angular movement with respect to the other, resilient means tending to resist relative movement and to urge the shafts toward each other, opposed feed rolls carried by the respective shafts and adapted to grip the margin of the sole therebetween, means for rotating the shafts and rolls to move the sole margin lengthwise in a substantially vertical direction, a pair of guides adapted to bear against the edge of the moving sole on opposite sides of the unrestrained path of movement of its gripped margin, to cause the sole to revolve with its edge in constant engagement with said guides, one of said guides comprising a roller which is turned by contact and means for applying blacking to said roller to black said edge, and independent means for adjusting the position of the respective guides with respect to the feed rolls.
